Can obsidian cut through diamonds?
Cutting edge Obsidian – a type of volcanic glass – can produce cutting edges many times finer than even the best steel scalpels. At 30 angstroms – a unit of measurement equal to one hundred millionth of a centimeter – an obsidian scalpel can rival diamond in the fineness of its edge.
Is diamond or obsidian sharper?
Surprising Things about Obsidian Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts.
Can obsidian blades cut through cells?
TIL Obsidian blades are so sharp (3 nm thickness) that, on a cellular level, obsidian knives will cut between cells rather than tear the cells as steel knives would do.
What is the sharpest thing in the world?
The sharpest object ever made is a tungsten needle that tapers down to the thickness of a single atom. It was manufactured by placing a narrow tungsten wire in an atmosphere of nitrogen and exposing it to a strong electric field in a device called a field ion microscope.
What was the sharpest sword ever made?
Former engineer turned master swordsmith makes the world’s sharpest sword. The sharpest swords in the world are being forged in Texas, where a former “bored engineer” has stunned Japanese experts with his handiwork. Daniel Watson runs Angel Sword, creating artistic weapons which sell from $2,000 to $20,000.
Does obsidian exist?
obsidian, igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. Obsidian is extremely rich in silica (about 65 to 80 percent), is low in water, and has a chemical composition similar to rhyolite. Obsidian has a glassy lustre and is slightly harder than window glass.
Do doctors use obsidian?
Obsidian is used by some surgeons for scalpel blades, as well-crafted obsidian blades have a cutting edge many times sharper than high-quality steel surgical scalpels, the cutting edge of the blade being only about 3 nanometers thick. Surgeons must be very careful to cut only soft tissues with the obsidian scalpel.
What is the sharpest knife ever?
Obsidian knife blades: overkill for slicing your sandwich. The thinnest blades are three nanometres wide at the edge – 10 times sharper than a razor blade. These are made by flaking a long, thin sliver from a core of obsidian (volcanic glass).
What’s tougher than a diamond?
Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.
Do surgeons still use obsidian scalpels?
Interestingly, Stone Age blades are still used for cutting in modern surgery. Believe it or not, but the sharpest knives produced lately are mounted with stone flakes made of obsidian. A handful of surgeons are benefiting themselves by using them for fine incisions that they say heal with minimal scarring.
How sharp is black obsidian?
Obsidian Color Deep black or blackish green Fracture Conchoidal Mohs scale hardness 5–6 Luster Vitreous.
Can obsidian cut atoms?
Since obsidian will fracture down to a single atom, it is claimed to have a cutting edge five hundred times sharper than the sharpest steel blade, and under a high magnification microscope an obsidian blade still appears smooth, whereas a steel blade has a saw like edge.
Who made the sharpest sword?
Damascus swords — sharp enough to slice a falling piece of silk in half, strong enough to split stones without dulling — owe their legendary qualities to carbon nanotubes, says chemist and Nobel laureate Robert Curl.
Why are Japanese blades so sharp?
Most quality Japanese knives can be sharpened to a much finer angle at the cutting edge because of the harder steel. This contributes to a sharper knife that slices and cuts through food with ease and with the additional benefit of less pressure on the muscles and joints in the hand.
What is the sharpest tool?
The phrase not the sharpest tool in the shed means someone who is thought to be unintelligent in some way; slow to perceive or understand something. Note: There is a similar expression with the same meaning as this one that goes “(he/she’s) not the brightest bulb in the box.”.

What is the strongest sword ever made?
Of all the famed Masamune swords, the Honjo Masamune is perhaps the most legendary. The blade earned its status as the greatest sword ever fashioned by splitting the helm of Honjo Shigenaga, who captured the sword after nearly being killed by its brilliant sharpness.
Is there fake obsidian?
Obsidian. This can be a particularly insipid fake; true Obsidian is volcanic glass, which is obviously quite similar to man-made glass, both in appearance and composition. Some pieces are easy to identify as fakes – primarily due to their clarity. Fake Black Obsidian is very hard to identify, unfortunately.
Is purple obsidian real?
Purple Obsidian – Known as the “Stone of Psychics” this variety of Obsidian will benefit the higher chakras and help elevate any psychic endeavor. Note: While this stone is manmade the base elemental material is identical to that of natural volcanic glass.
